HAND STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent NO. 645,414, dated March 13, 1900.

Application filed December 14, 1899- Serial N0.740,Z65. (No model.)

To all whom it may concern:

Be it known that I, FRED D. WRIGHT, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Hand Street-Sweepers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in hand street-sweepers, having particular reference to the detail construction thereof.

My object is to produce a hand streetsweeper which is cheap and durable in its construction, easy of operation, and of great utility; and to that end my invention consists in the several new and novel features of construction and operation which are hereinafter described, and specifically set forth in the claim hereunto annexed. It is constructed as follows, reference being had to the accompanying drawings, in which- Figure 1 shows a side view of the sweeper complete, ready for operation, a portion of the shell being broken away, showing the brush and scraper. Fig. 2 is a longitudinal section through the center of the brush. Fig. 3 is a cross-section on line w :0, Fig. 2. Fig. 4 is a view of the portion of the front end of the shell, showing the plate in which the brush is mounted. Fig. 5 is a vertical section, enlarged, on line y y, Fig. 4. Fig. 6 is a View of the rear portion of the shell, showing the scraper. Fig. 7 is a View of a portion of the scraper.

Similar letters of reference indicate corresponding parts.

a is a shell or outer casing constructed substantially as shown, enlarged at its. front end, as shown at a, to afiord a housing for the rotating brush a. The brush is made in two sections, the outer ends being journaled in the plate located upon the outside of the shell, and the inner ends being journaled in the knuckle-joint arm I), which is secured to the upper face of the shell, as shown in Fig. 3.

0 is a vertical slotway in the housing a for the vertical adjustment of the rotating brush. To raise or lower the brush, I remove the screws in the plate a, and after having raised the brush, by allowing its journal to move in the slotway to the desired position, I refasten the plate a.

The brushes are driven by sprocket-wheels I), mounted on the outer end of the shaft carrying the brushes, which engages with a sprocket-chain 19, passing over the driven sprocket c, secured fast to the driving-wheels c in the ordinary way.

01 are uprights secured to the top of the rear portion of the shell and support a dust receptacle or bag d, and e is a handle by which the sweeper is pushed. Upon each side of the shell and beneath the brushes is mounted a guide-wheel f, adapted to be adjusted vertically by raising or lowering the arm f, upon which it is mounted. This arm f is pivoted at f and held in position by a screw or bolt f.

Just rear of the brush is a scraper m, journaled by the gudgeon m in the casing, the forward end passing down adjacent to the ground and the rear end resting upon the front end of the removable dust-pan n. This scraper is constructed with rearwardly-extending forks m, so that it may be reversed and used in sweeping or raking up leaves, if desired. The forward end of the scraper is adjusted vertically by the arm n.

n is a dust-pan supported removably in the rear end of the outer casing. The removable dust-pan n is drawn out by means of a handle 0 and lifted by a bail o.

p are forward and slightly laterally extending curved'shears, which throw the dirt inwardly in the track of the sweeper when near the curb or allow the sweeper to be run up against the curb at right angles and prevent its being damaged.

Having described my invention, what I claim, and desire to secure by Letters Patcut, is-

A street-sweeper comprising a shell having a removable dust-pan in its rear end, its forward end enlarged and rotating brushes mounted therein, and means for rotating said brushes by the movement of the streetsweeper, the inner end of said brushes being mounted upon a knuckle-joint arm, and means for raising and lowering said brushes, and a scraper mounted within the shell, and means for raising and lowering its forward end, its rear end resting on the forward end of the removable dust-pan, substantially as described for the purposes set forth.

In witness whereof I have hereunto set my hand this 5th day of December, 1899.
